I've used a lot of different mascaras, from higher end (benefit they're real, clinique) to high street and I have to say this is the one I always come back to. It's nice and affordable (I got this for £5 in the black Friday sale!) And gives me the most voluminous, dark, thick and elongated lashes in just one layer! I love the brush shape - the concave side is perfect for getting product onto your lashes to make them look nice and thick, and the convex side perfect for elongating your lashes. Honestly if you haven't tried this yet, give it a go - it's a big hit on YouTube and with beauty bloggers too and it really does live up to the hype.
